你好，我想我需要一些帮助。我正在使用Bitbucket。我在Windows10中安装了Git和Gitbash以及Cygwin。我正在尝试从cmd窗口进行克隆。
我希望能够从Gitbash、cygwin和cmd窗口运行git命令。。。这可行吗？无论如何，现在什么都不起作用，所以我开始使用Windows cmd。
我的SSH配置文件位于以下位置：c:\Users<我的用户id>。ssh\config
Host <info removed>
HostKeyAlgorithms +ssh-rsa
PubkeyAcceptedAlgorithms +ssh-rsa
我的SSH文件夹中还有两个SSH文件：
- id_rsa
- id_rsa.pub我遵循了以下指南：https://support.atlassian.com/bitbucket-cloud/docs/set-up-an-ssh-key/
使用以下命令生成：
C:Users<info removed>.ssh>ssh-keygen
Generating public/private rsa key pair.
...
no passkey added
...
将id.rsa.pub中的公钥上传到Bitbucket，并将其与SSH密钥放在一起。
我在这里有一个sshd_config：C： \ProgramData\ssh\shd_config没有做出任何更改，但我认为一些有趣的行是：
#PubkeyAuthentication yes
#PasswordAuthentication yes
#PermitEmptyPasswords no
获取WindowsCapability-联机|？类似名字的"；openssh*"；…提供为服务器和客户端安装的
运行一些附加命令：
设置服务ssh代理-StartupType自动
启动服务ssh代理
ssh添加$HOME\.ssh\id_rsa
C:Users<my user id>sourcerepos>git clone ssh://<info removed>.git --config core.sshCommand="ssh -v"
Cloning into 'myRepo'...

我也不明白什么时候、哪里以及为什么使用所有配置文件。
听起来id_rsa.pub还没有添加到Bitbucket中，但它已经添加了！
这行"；读取配置数据/etc/ssh/ssh_config"；当我使用Windows时会感到困惑。
所以求你了，我真的需要一些帮助来完成这项工作。
从这个线程和"SSH-RSA密钥被拒绝；无相互签名算法">
为了重新启用ssh-rsa支持，在受影响的ssh客户端的配置文件中插入以下行可以重新启用此算法(
%USERPROFILE%.sshconfig(：PubkeyAcceptedKeyTypes+Sh-rsa
或者，您可以生成ed25519公钥算法
ssh-keygen -t ed25519 -P ""
OP fishfloat在评论中报告重新安装了Git For Windows，选择使用外部SSH客户端并解决了问题。
